These supporting .devicescoinone place to another.This carrier is mountprise a seriesot supporting bars ea ch piv-l ed forvertical movements to raise and lower oted at its lower end at 30 to anangle bracket pivotal points the supporting bars 28 extend upwardly insubstantially parallel relation, and adjacent their upper ends thesebars pass through U-shaped guide members 34 attached to the horizontalbars 2 and also engage a transverse angle bar 36 secured to thehorizontal bars 2 of the frame, as shown in Fig. 1.

In order to hold the brick supporting fingers in horizontal position,thesupportingY bars 28 are latched in their upper positions shown inFig. 1. The latch mechanism comprises a transverse rock shaft 38 mountedto turn in bearing blocks 40 attached to the supporting frame. Thisshaft carries a. series of latch fingers or dogs 42 each of which isarranged to engage in a notch 44 in the corresponding supporting bar 28.The rock shaft 38 is yieldingly actuated to engage the dogs 42 in therespective notches in the supporting bars 28 by means of one or morecoiled springs 46 each connected at one end to an arm 48 projecting fromthe rock shaft and at the other end to a point on the frame. The rockshaft 38 is turned in a direction to disengage the dogs 42 from thenotches in the supporting bars by means of a cable or chain 50 attachedat one end to an arm 52 secured to the rock shaft.

The dogs 42 and the notches 44 in the supporting bars are preferablyshaped so that when the dogs are engaged in said notches and a stack ofbrickis supported upon the fingers 22, the friction between the ends ofthe dogs and the contacting faces of the vnotches will prevent thedisengagement of the dogs from the notches until the load upon thesupporting bars 28 is relieved. This will prevent the accidental releaseof the load of bricks carried by the fingers until the fingers f arebrought into engagement with the hori- Zontal support upon which thebricks are to be placed by the descent of the carrier.

VIn order that the fingers 22 may be swung upwardly to a slight degreewith relation to the frame when the fingers engage the support uponwhich the bricks are to be placed, the fingers are preferably madesomewhat wider adjacent their outer ends, as shown in Fig. l. With thisconstruction when the carrier descends vertically, the wider outer endsof the fingers will first engage the horizontal support, and the furtherdescent of the carrier will then cause the fingers to swing upwardlyslightly with relation to the frame thereby relieving the pressureexerted by the bars 28 upon the outer ends of the dogs 42.

Other constructions may be employed for causing the outer ends of thebrick supporting fingers to engage first the support. Thus the fingersand the latching mechanism therefor may be so constructed that when thefingers are latched in their upper or brick supporting positions, theangle between the same and the upright bars 4 will be greater than aright angle. This will cause the fingers to droop slightly with relationto the frame when carrying a load of bricks and the outer ends of thelingers will first engage the support upon which the bricks are to beplaced.

The bricks are prevented from accidentally engaging between thesupporting bars 28 by means of suitable abutments which also serve tolimit the movement of the fingers 22 beneath the stacked bricks. Oneof'these abutments consists of one side plate of the angle bar 26. Anabutment plate 54 also is attached to the supporting bars 28 preferablyby welding the same to the bars, as shown in Fig. 1. The space betweenthe lower edge of the abutment plate 54 and theadjacent side plate ofthe angle bar 26 is filled by a curved plate 56. This curved plate 56 isattached to the adjacent side plate of the cross bar 26 and may consistof an. extension of said side plate. As shown in the drawings, thiscurved plate is attached to the angle bar 26 by means of attachingplates 57 extending across the joint between the curved` plate 56 andthe adjacent side plate of the angle bar and welded both to the curvedba-r and the angle bar. The curved plate 56 is provided with slotsf58 toreceive the supporting bars 28 thereby forming the curved plate withportions projecting between the supporting bars, as shown in Fig. 2. Thecurved formation of the plate 56 prevents the bricks from becomingdisplaced between the same and the supporting bars V28 when the fingers22 are in lowered position, as shown indotted lines 1n Fig. 1.

The construction shown in Figs. 3 and 4 is substantially the same asthat shown in Figs. 1 and 2 except that the supporting bars'28 areconnected in a somewhat different man'-V ner to the fingers 22, and adifferent con# struction is provided for preventingthe bricks frompassing between the supporting bars. In the construction shown in Figs.3 andA 4 the supporting bars 28 are connected in spaced relation bymeans of an abutment plate 60 to which thebars are preferably welded.The bars are pivotally connected at 62 to the fingers 22 by means of ahinge 64 one member of which is secured to the abutment plate 60 and theother member of which is secured to the angle bar 26. In thisconstruction the abutment plate 60 and the adjacent side plate of theangle bar 26 are arranged sufliciently close together to pre` vent theengagement of bricks between the same.

The construction shown in Figs. 5 and 6 is similar to that shown inFigs. 1 to 4, inclusive, except that the supporting bars 28 areconnected in a different manner with the lingers 22 and that a differentconstruction is employed for holding said bars in elevated positions. Inthe construction shown in Figs. 5 and 6 the bars 28 are connected byLamme an abutment plate 66 secured to said bars. The bars are pivotallyconnected at 68 with the fingers 22 by means of a hinge comprising hingeplates 7 0 and 72. The hinge plate 72 preferably extends across theseveral ngers 22 and is connected to each finger by means of anglebrackets 76. The hinge plate preferably extends across the severalsupporting bars 28 and is secured to each of said bars, as shown in Fig.5. The abutment plate 66 and the hinge plate 70 prevent the passage ofthe bricks between these supporting bars.

The supporting bars 28 are respectively provided at their upper endswith a projection 78 arranged to engage the upper edge of the verticalside plate of the angle bar 36 which extends across and is secured tothe horizontal bars 2 of the frame. The position of each of thesupporting bars 28 is controlled by means of a bar 80 having therein aseries of slots 82 through which the supporting bars`28 project. Thecontrolling bar 8O is carried by arms 84 secured to the rock shaft 86mounted in bearing blocks 88 secured to the frame. With thisconstruction, upon turning the rock shaft 86 to the right, Fig. 6, thesupporting bars 28 will be moved in a direction to disengage theprojection 78 from the angle bar 36thereby releasing the supporting barsand the fingers 22. To the rock shaft is attached an arm 90 to which isconnected a cord or cable 92 for actuating the rock shaft in a directionto disengage the projection 78 from the angle bar 36. The

rock shaft is actuated in the reverse direction to restore thesupporting bars to positions to place the projection 78 above the upperedge of the angle bar 36 by means of a coiled compression spring 94interposed be.

tween the arm 90 and the frame.
